What was found
AFTER T/O FROM YXH FOR YQL, CREWS ATTEMPTED TO RETRACT L/G. GEAR WOULD NOT RETRACT SO THE CREW SELECTED OVERRIDE. THE GEAR RETRACTED BUT NLG DID NOT FULLY RETRACT INTO NOSE GEAR BAY. CREWS THEN SELECTED GEAR EXTENSION AND RETURNED BACK TO BASE WITH NO FURTHER PROBLEMS. MX FOUND THAT L/G GEAR SAFETY SWITCH WAS NOT BEING MADE DUE TO L/G BEING IMPROPERLY SERVICED NIGHT BEFORE. IT HAS BEEN NOTED BEFORE THAT N/G INTERNAL FLOATING PISTON ON OCCASION (ALL JETSTREAM NOSE GEAR ASSY`S ) WILL HANG UP AND STICK DURING SERVICE GIVING AME A FALSE INDICATION OF PROPER SERVICE. AFTER REVIEW FOUND ALTERNATE METHOD IN MM. THAT WILL RECTIFY THIS PROBLEM. ALL OF OUR MX TO BE NOTIFIED. GEAR RESERVICED AND NO FURTHER FAULTS
